摘 要: Recently, much concentration has been focused on chiral macrocyclic amides that bear the dual features of macrocyclic polyamines and oligopeptides, which can act as both hydrogen bond acceptors and donors and can form complexes with cation, anion or neutral molecules, so as to have potential applications for enantiomeric recognition and enantiomeric separation. In light that the more rigid the macrocyclic molecule, the better the enantiomeric recognition, and macrocyclic receptors possessing C2 symmetry usually show higher enantioselectivity than those of C1 symmetry, we chose L-proline, which possesses a unique and rigid pyrrolidinyl group, as starting material to synthesize a new class of novel chiral macrocyclic dioxopolyamines of C2 symmetry. ……
